Is everything ok at home Old Khaki?

I recently ordered 4 x Golf Shirts from Old Khaki online, as I have done previously on many occasions. My size has stayed exactly the same so I was comfortable doing so again. I ordered the exact same cut/style and the 4 shirts arrived in various colours. Two of the shirts fit perfectly, however, two don't. I can fully understand if I may have chosen different cuts or styles, but it is exactly the same. This is very frustrating. What makes things worse, it took a week from logging the return to the collection. Is everything ok at home Old Khaki?
